HMA Pavement Mix Type Selection Guide Introduction Background Our nation’s roadway system is critical to our economy. Hot Mix Asphalt (HMA) pavements consti-tute a large part of our nation's surfaced roads. HMA pavements serve in a multitude of traffic and environ-mental conditions, demanding that the materials and
Following placement of the aggregate, the mixture is rolled and compacted to provide a drivable, dust-free surface. This type of pavement is common on light- to medium- volume roads that may or may not already have an existing bituminous surface. MATERIALS. The components of asphalt concrete include asphalt aggregate and asphalt binder.
OptiPave is an asphalt-based emulsion pavement surface seal designed to seal and protect asphalt roads while replenishing the pavement binder that is lost through oxidation and weathering. OptiPave beautifies, protects, and extends the service life of asphalt pavement while providing a rich, black, “like new” appearance.
